I restarted our cluster because a network interface was acting odd and now our ganglia will not work. I believe the problem is related to gmond. It is running at about 20% of a processor, and the head node spits out data to the port very quickly.
Anyway beyond the high gmond problem listed above. My other symptoms are: Error message on web pages: Cannot find any metrics for selected cluster "computation cluster", exiting. Check ganglia XML tree (telnet 127.0.0.1 8652) Typing ganglia at the prompt never fishes and has to be cleared with a CTRL-C. There seems to be a large amount of multicast traffic. Any Clues?
